摘要
论文基于单片机与电子电力技术,采用Boost直流斩波电路作为DC-DC变换器的主要部分。以STC12C2052AD处理器作为整个系统的主控器并且增加了对主电路电流、电压的采样反馈,实现过流保护和闭环PWM控制。该文对系统的硬件、选型、软件控制的实现均有较为详细的阐述,围绕单片机和开关电源技术进行的小功率通用开关稳压电源的设计。
The thesis based on MCU and power technology,uses Boost DC chopper circuit as the DC-DC converter major part of the main circuit. The subject uses the STC12C2052AD as the main controller of the all-whole system, and it increases the sampling and feedback of the current and voltage of the main circuit to achieve over-current protection and closed-loop PWM control. In this paper, the hardware of system, selection, the realization of software control are described in detail. Design of low- power general-purpose switching power supply focus on MCU and power technology.
